Title: Improvements in and relating to wire feeding devices
IPC: B23K9/133
Filed: 1938-10-17
Abstract: 520,047. Uniting by fusion ; rod feeds. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 17, 1938, No. 30015. Convention date, Oct. 16, 1937. [Classes 83 (iii) and 84 (iv)] A feed device, particularly for feeding electrode wire in an automatic arc welding head, comprises feed rolls forming a tapered gap between their adjacent working surfaces and means located between them and biased towards the more constricted portions of the gap for holding the wire in engagement with the working surfaces of the rolls. Wires of various shapes and sizes may thus be fed without adjusting the feed rolls relatively to each other. In the form shown, which is applied to an automatic arc welding head, a pair of knurled tapered feed rolls 11 are carried, one by a main shaft 12 mounted in bearings 14, 15, 32 and driven by worm gear 20, 21 from an electric motor 19 and the other by a shaft 13 which is mounted in ball bearings 25, 26 in a two-part totally enclosed gear box 27, the shafts 12, 13 being connected by speed gears 30, 31. The rolls are secured to their shafts by screws 44 and bevelled plates 43, Fig. 5, which force them into engagement with washers 45 engaging the inner portions of the bearings 32, 26. The gear box is adjustable round the shaft 12 by a worm wheel 33 and a worm carried by an elastic shaft operated by one of the hand wheels 38, 39 so as to adjust the angular positions of the wire in a predetermined plane. The wire 10, which passes through guides 49, 50 carried by bosses 52, 53 forming part of the gear box is pressed between the rolls 11 by a roll 59 carried by a spring-pressed arm 57 pivoted at 58 in lugs 56 on the boss 52. An adjustable stop 61 is provided on the arm 57. In order to adjust the position of the guides in accordance with the diameter of the wire they are provided with offsets 51, Fig. 6, and are reversible in slots in the bosses and secured in position by straps 54, 55. The bearings 14, 15 of the shaft 12 are mounted in a two-part casing 16, 17. The lubricant in the sections 16, 17 is lighter than that in the gear box and to prevent passage of lubricant between the gear box and sections 16, 17, grooves 40, 41 are provided with fibrous grease. Packing 42 is also provided between the rim of the gear box and the section 17. The section 17 is provided at each side with a boss 71 on either of which is inserted a clamp 72 for engaging the arm portion 68 of a bracket, so that the head may be angularly adjusted about the longitudinal axis of the arm. This arm is in two parts insulated from each other, the second portion having a flange by which the head may be attached to a support. Current may be supplied to the arms through terminal 63 and a nozzle 62. Specification 516,837, [Group XXXV], is referred to. The Specification as open to inspection under Sect. 91 states that the feed rolls may be of metal or non-metal and need not be tapered. This subject-matter does not appear in the Specification as accepted.

Abstract: 505,563. Doubled yarns; mixed fabrics. ELLIS, G. H., and MONCRIEFF, R. W. Nov. 10, 1937, No. 30853. [Classes 120 (iii) and 142 (iv)] [Also in Group IV] Textile products capable of being dyed a solid shade with cotton dyestuffs are obtained from two or more types of cellulosic yarns having different affinities for such dyestuffs by introducing into the yams having the greater affinity for such dyestuffs, before forming the products, such a proportion of organic ester or ether radicles that their affinity is reduced to that of the yarn having the lowest affinity. Textile products mentioned are doubled yarns, woven, knitted or netted fabrics or composite products such as hose having tops and feet of cotton and legs of artificial cellulosic yarn. In the case of woven fabrics, the two types of yarn may comprise the weft and warp respectively or both types may be present in the weft and /or warp. Cellulosic yarns mentioned are cotton, linen, and regenerated cellulose yarns obtained by the viscose, cuprammonium and nitrocellulose processes and by the saponification of yarns made of cellulose acetate or other organic esters of cellulose. The organic ester or ether-radicles mav be introduced into the yarns by treating them with acetic, propionic or butyric anhydrides, acetyl chloride, ethyl chloride, or dimethyl sulphate, under such conditions that the structure of the yarns is not changed. In an example, cotton is acetylated under such conditions as to produce about 2 per centincrease in weight and then woven into fabric together with regenerated cellulose yarns.

Abstract: 1,235,439. Feeding webs. STANDARD TELEPHONES & CABLES Ltd. 18 June, 1969, No. 30938/69. Heading B8R. In an arrangement for controlling the tension and acceleration of strip material, e.g. insulating paper for electrical conductors, when unwinding from a reel or pad 1, the pad is supported on a stop 4 in such a manner as to not to increase the tension in the strip 15 being unwound in the direction C. and is provided with a rotatable centre 2 which moves in guides 5 to approach the stop 4 as the diameter of pad 1 decreases; brake pads 6, e.g. of tungsten carbide, engage both sides of the pad 1 at a position near its circumference, being operable by a mechanism including brake calipers 7 attached to torsion bars 8 mounted in bearing blocks 9. A braking force, derived from a closed loop control system, is transmitted to the bars 8 and hence to the pads 6 by means of a lever 14, a balancing arm 12 and torque arms 10 (Fig. 2, not shown), whereby the pad 1 is correctively braked so that the back-tension in the strip 15 is maintained constant no matter how the pad diameter varies. So that the force required to support the pad 1 on the stop 4 does not add to the strip tension, the stop 4 may be in the form of a gas bearing; alternatively the centre 2 may be connected to a counterbalancing mechanism, or it may be constrained to run down an inclined plane rather than vertically downwards.

Abstract: 343,112. Recording-apparatus. WILLIAMS, W. E., Kildare, Ethelbert Road, Bromley, Kent. Oct. 12, 1929, No. 31057. [Class 106 (iv).] Photographic recorders.-In apparatus for recording sound vibrations, electrical oscillations, &c. an optical system is provided in association with a vibratory mirror for eliminating the effect upon the record of one or other of the tilting or translatory components of movement of the mirror. As shown in Fig. 1 a plane mirror M is attached to the coil that is tilted by electromagnetic action due to the pulsations flowing therethrough and is placed near an objective lens system O such as in the Abbe backreflecting condenser. Light from a point source diaphragm S is passed through a totally-reflecting prism P so placed that the beam emerging from the objective is a parallel beam which is reflected as a parallel beam and focussed by the objection on a moving plate or film R. To avoid refraction effects of the prism P, Fig. 3, the two surfaces r<1>, r<2> are made spherical instead of plane. The plane mirror may consist of a thin film of silver or other metal deposited on a cleaved rock salt plate supported on a wire frame, the rock salt being dissolved away leaving the mirror rigid. In a modification a pure translatory movement may be utilized by arranging two mirrors at right angles to one another on the coil as shown in Fig. 2, the coil being mounted to prevent any possibility of a tilt. By employing an arrangement of three mirrors each perpendicular to its neighbour all effects of tilting in any plane are obviated. For this purpose a tetrahedron of glass on a symmetrical triangular base with an effective apex angle of 90‹ may be provided.
